From here on we start to authenticate uploaded file request before
serving this files in production. This involves allowing NGINX to
pass on these file requests to Django for authentication and then
serve these files by making use on internal redirect requests having
x-accel-redirect field. The redirection on requests and loading
of x-accel-redirect param is handled by django-sendfile.
NOTE: This commit starts to authenticate these requests for Zulip
servers running platforms either Ubuntu Xenial (16.04) or above.
Fixes: #320 and #291 partially.
This comment didn't really explain things unless you were looking at
the code, and/or had a strong enough association for what "cn" means
that it was obvious what must be meant. Maybe this will be clearer.
There is one other meaningful key, which is optional: "short_name",
for which I guess a typical value if supplied would be "uid" or
"userid". I'm not sure we really do much with a user's `short_name`,
though, so didn't add a comment for it. When this key is omitted,
we set the user's `short_name` to the same thing as `full_name`.
It's too easy to go over the rate limits when using the webapp.
The correct fix for this probably involves some changes to which
routes get covered by what sort of rate limit, but for now, just
increase the limits.
The original code made a 3/4-hearted effort to generically accommodate
more banners/"panels" later, but named itself after the first one made.
[greg: expanded commit message.]
Different formats for configuration files have a wide variety of ways
of representing lists; so if you're not accustomed to Python syntax,
or aren't thinking of this file as Python code, the syntax for several
ALLOWED_HOSTS entries may not be obvious. And this setting is one
that an admin is likely to want to touch quite early in using Zulip.
So, demonstrate a multi-element list.
For similar reasons, demonstrate an IP address. This one is in a
range reserved for documentation (by RFC 5737), like `example.com`.
For now, this does nothing in a production environment, but it should
simplify the process of doing testing on the Thumbor implementation,
by integrating a lot of dependency management logic.
Gmail is a bad example for outbound email; use a generic example.
Also leave the `= None` default out of the config file, as it's
redundant with DEFAULT_SETTINGS in our internal settings.py ; and
explain in the latter why we don't mention the other SMTP settings.
Since we need KaTeX to be available for zerver/lib/tex.py and
static/third/katex/cli.js to be able to shell out to it. However, for
some reason, the KaTeX we bundle using Webpack doesn't seem to be
importable by Node (and it's also kinda a pain to find its filename
from `cli.js`).
So, we work around this by just using the legacy system for KaTeX.
Something similar is needed for zxcvbn.js, in order to support the
settings_account.js use case (basically deferred loading of this
file); that requires JS code to have access to the correct path for
zxcvbn.
Stripe Checkout means using JS code provided by Stripe to handle
almost all of the UI, which is great for us.
There are more features we should add to this page and changes we
should make, but this gives us an MVP.
[greg: expanded commit message; fixed import ordering and some types.]
There are two different things you need to patch in order to get error
emails (at `/emails`) in dev. Flip one of them in dev all the time,
and make the comment on the other a bit more explicit.
This name hasn't been right since f7f2ec0ac back in 2013; this handler
sends the log record to a queue, whose consumer will not only maybe
send a Zulip message but definitely send an email. I found this
pretty confusing when I first worked on this logging code and was
looking for how exception emails got sent; so now that I see exactly
what's actually happening here, fix it.
This line was added in e8ab7cd1a as a desperate measure to get the
`set_loglevel` helper to successfully suppress the `zulip.send_email`
logs.
In fact, the reason that just setting `level` there wasn't doing the
job had nothing to do with `propagate`, which doesn't interact with
`level`. (See the long block comment in `zproject/settings.py`,
searching for "Python logging module", for my attempt at concisely
explaining these semantics.) Rather, our setting for `level` was
getting clobbered by the use of `create_logger`; and setting
`propagate` to False worked by completely suppressing all logs to
`zulip.send_email` and descendants from reaching the normal handlers,
regardless of the log messages' levels.
Now that the `create_logger` issue is fixed (see a few commits before
this one), drop that.
Because calls to `create_logger` generally run after settings are
configured, these would override what we have in `settings.LOGGING` --
which in particular defeated any attempt to set log levels in
`test_settings.py`. Move all of these settings to the same place in
`settings.py`, so they can be overridden in a uniform way.
These aren't of much use without the corresponding secrets (despite us
calling one of them a "key", both are public IDs), which are in my
personal dev-secrets.conf. So, remove them.
I had this commit applied in order to test what became 90944983f...
and then I accidentally included it in what I pushed, as 0fa9a489d.
Oops.
This adds custom CSS through JavaScript for things that do not
scope well and will override other inherited styles.
This should ONLY be used for problematic CSS that has no obvious
or easy CSS-only solution.
(Specifically, we need this for the "default link" styling, which is
hard to override because we don't want to start winning ties due to
specificity that we would not have won in the light theme).
[Modified by greg to (1) keep `USERNAME_FIELD = 'email'`,
(2) silence the corresponding system check, and (3) ban
reusing a system bot's email address, just like we do in
realm creation.]
Originally this used signals, namely SIGRTMIN. But in prod, the
signal handler never fired; I debugged fruitlessly for a while, and
suspect uwsgi was foiling it in a mysterious way (which is kind of
the only way uwsgi does anything.)
So, we listen on a socket. Bit more code, and a bit trickier to
invoke, but it works.
This was developed for the investigation of memory-bloating on
chat.zulip.org that led to a331b4f64 "Optimize query_all_subs_by_stream()".
For usage instructions, see docstring.
Tweaked by tabbott to move changes from the next commit that are
required for this to pass tests into this commit.
Note that this exports a few items that were not previously exported.
This fixes some subtle JavaScript exceptions we've been getting in
zulipchat.com, caused by the system bot realm there not being "zulip"
interacting with get_cross_realm_users.
I probably should have just done this in the original implementation;
there's only a small downside in the form of an extra database query
when trying to authenticate a user who doesn't exist.
Structurally, the main change here is replacing the `clean_username`
function, which would get called when one accessed
self.cleaned_data['username'] with code in the main `clean` function.
This is important because only in `clean` do we have access to the
`realm` object.
Since I recently added full test coverage on this form, we know each
of the major cases have a test; the error messages are unchanged.
This deletes the old mock-covered test for this, which was mostly
useless. We have a much less messy test, which we extend to provide
the same test coverage the old one did.
While the result was the same before, this makes it more obvious.
This uses the to-markdown.js library to do all the hard work of
parsing HTML and turning it into markdown and not e.g. uploaded files.
Tweaked by tabbott to better scope when it activates to just include
pastes of HTML content.
Fixes#5853.
We created this redundant pair of conditionals in a preceding commit,
in order to match the indentation of an `except` block so as to slice
the diffs extra finely as we're refactoring auth code.
This lets us delete some duplicate code, since common_get_active_user
handles an account in the wrong subdomain for us.
Also lets us delete the now-unused common_get_active_user_by_email.
This way, we don't attempt to evaluate whether the user's account is
active (etc.) until after we've checked the backend is enabled. This
won't change the result of actual auth, but feels more readable.
This is a behavior change, though we don't check the value in the
caller regardless. It just seems more logical for us to correctly
report to the caller whether the Google auth itself was valid
unconditionally.
This code path was only required because we had remote_user set as a
positional argument here, and thus we'd be running this auth backend's
code when actually using another auth backend (due to how Django auth
backends are selected based on argument signature).
This require some care to ensure we still provide the same nice error
messages for the case of a user who has an account, just not with this
organization.
Also, we fix the fact that the docstring was (and I think always has
been) at best confusing and perhaps even inaccurate.
Now we have moved the `do_auth` function to `SocialAuthMixin`. Instead
of overriding `do_auth`, derived class is now expected to override
`get_authenticated_user`.
`do_auth` now contains code which is expected by all backends.
Storage limititations are only set on the value of
a config entry, since this is the only user-accessible
part of the schema. Keys are statically set by each
embedded bot.
This endpoint will allow us to add/delete emoji reactions whose emoji
got renamed during various emoji infra changes. This was also a
required change for realm emoji migration.
This commit was tweaked significantly by tabbott for greater clarity
(with no changes to the actual logic).
Note from tabbott: While this initial version is experimental and
definitely incomplete, we expect to have a solid version done over the
next few weeks (after more refactoring). We're merging this now to
make it easy to test both versions when refactoring our CSS.
Fixes#267.
These are new:
new-user-bot
emailgateway
Our cross-realm bots are hard coded to have email addresses
in the `zulip.com` domain, and they're not part of ordinary
realms.
These have always been cross-realm, but new enforcement in the
frontend code of all messages having been sent by a known user means
that it's important to add these properly.
The warning here means that the admin can't really act on this yet if
they want to disable email auth, which is likely among admins that
want to make any changes here. And for admins who don't, this is an
extra thing to read and make a decision about before they can get a
server running. See #6985.
Conversely, we already discuss auth backends right at the top of the
`prod-customize` doc, which is linked under "Next steps" at the end of
these instructions.
The warning about EmailAuthBackend is important; but we can move it to
the config file right next to the setting, and then it's available
right when it's actionable, which is if the admin is actually thinking
about changing the setting.
For some historical reason we'd had the Postgres documentation on
valid SSL modes copied into the Zulip settings.py template file. This
fixes that historical artifact.
This change prepares us to have the server send avatar_url
of None when somebody wants a gravatar avatar (as opposed
to a user-uploaded one).
Subsequent commits will change behavior on both the server
and client to have this happen. So this commit has no-op
code for now, but it will soon use the fallback-to-gravatar
logic.
The control panel on the Google side doesn't seem to match the
instructions we have; it looks pretty 2017 to me, so I imagine
it's had a redesign since the instructions were written.
Also, in dev, EXTERNAL_HOST is now a port on zulipdev.com, not on
localhost.
Update these instructions for those developments, and edit lightly.
In dev, recommend setting in `dev_settings` instead of in
`prod_settings_template`; that feels to me a little more reflective of
the actual intent, and the effect should be equivalent.
The main limitation of this version is that it's controlled entirely
from settings, with nothing in the database and no web UI or even
management command to control it. That makes it a bit more of a
burden for the server admins than it'd ideally be, but that's fine
for now.
Relatedly, the web flow for realm creation still requires choosing a
subdomain even if the realm is destined to live at an alias domain.
Specific to the dev environment, there is an annoying quirk: the
special dev login flow doesn't work on a REALM_HOSTS realm. Also,
in this version the `add_new_realm` and `add_new_user` management
commands, which are intended for use in development environments only,
don't support this feature.
In manual testing, I've confirmed that a REALM_HOSTS realm works for
signup and login, with email/password, Google SSO, or GitHub SSO.
Most of that was in dev; I used zulipstaging.com to also test
* logging in with email and password;
* logging in with Google SSO... far enough to correctly determine
that my email address is associated with some other realm.
This means one fewer thing the admin typically needs to read, absorb,
and make a decision about at install time.
The one way this change could hypothetically cause trouble is if the
admin wants to keep subdomains of EXTERNAL_HOST out of ALLOWED_HOSTS.
But while the subdomains often won't exist as domain names, it's hard
to imagine the situation in which they would exist but be under
someone else's control, or be doing something other than serving
Zulip realms.
This commit allows for the /api-new/ page to rendered similarly to our
/help pages. It's based on the old content for /api, but we're not
replacing the old content yet, to give a bit of time to restructure
things reasonably.
Tweaked by eeshangarg and tabbott.
This was part of the logic to handle EXTERNAL_API_PATH varying.
But also it was already no longer used -- it was only ever passed
into template contexts, as `external_api_uri`, and it'd been
overtaken there by `external_api_uri_subdomain`.
So, update our dev docs to reflect that, and eliminate the variable.
This setting isn't documented at all, and I believe nobody has used it
since the end of api.zulip.com in 2016. So we get to complete the
cleanup of this logic.
The HelpView class will render a directory as markdown with an index HTML
page. This however can also be used for other generics and applied to
the API pages as well, so change the class to a generic class and
specify the path templates and names.
Tweaked by tabbott and Eeshan Garg.
Our set_loglevel tool didn't set propagate to False, so just using it
directly wouldn't work unless the logger is explcitly declared in
zproject/settings.py, which this one isn't.
The cookie mechanism only works when passing the login token to a
subdomain. URLs work across domains, which is why they're the
standard transport for SSO on the web. Switch to URLs.
Tweaked by tabbott to add a test for an expired token.
Most of these have more to do with authentication in general than with
registering a new account. `create_preregistration_user` could go
either way; we move it to `auth` so we can make the imports go only in
one direction.
Lets administrators view a list of open(unconfirmed) invitations and
resend or revoke a chosen invitation.
There are a few changes that we can expect for the future:
* It is currently possible to invite an email that you have already
invited, it might make sense to change this behavior.
* Resend currently sends an invite reminder instead of resending the
original invite, this is because 'custom_body' was not stored when
the first invite was sent.
Tweaked in various minor ways, primarily in the backend, by tabbott,
mostly for style consistency with the rest of the codebase.
Fixes: #1180.
Now that every call site of check_subdomain produces its second
argument in exactly the same way, push that shared bit of logic
into a new wrapper for check_subdomain.
Also give that new function a name that says more specifically what
it's checking -- which I think is easier to articulate for this
interface than for that of check_subdomain.
Adds support to add "Embedded bot" Service objects. This service
handles every embedded bot.
Extracted from "Embedded bots: Add support to add embedded bots from
UI" by Robert Honig.
Tweaked by tabbott to be disabled by default.
This should help prevent confusion where new users find themselves on
the LDAP login form and click "register" because they know they don't
have an account. Whereas in fact, their account will be auto-created
if they just login, so there's no need for them to access it.
